Cause and action (in case of email)
Error type and cause
■ bounce
A bounce is an error that occurs when the receiving email server rejects a message. There are two types of bounce: soft bounce and hard bounce.
1. Soft bounce
This error occurs when an email is returned for one of the following reasons, even though the registered email address is correct and the email reached the recipient's server
- The mailbox was full
- The server was down
- Message size was too large.
2. Hard bounce
When a hard bounce occurs, the address is placed on the bounce list. This error occurs when an address is permanently rejected for the following reasons
- Invalid/incorrect email address
- Email address does not exist
- Once on the bounce list, the email will be dropped (discarded) when sent again to the recipient, and may not be processed for sending to the recipient's server.
■ Deferred
Deferred occurs when the receiving mail server requests that sending be stopped for a moment. Common causes include the following
- The recipient's mailbox is full
- Connection timed out
- MX records cannot be resolved
<Caution>
If by chance, due to bad timing, you temporarily fail to receive email, your email will be accepted as normal if the system is back to normal when you resend the email.
■ dropped
If you attempt to send an email to a recipient on the list below, the request will be dropped (discarded) by the SendGrid system.
- Bounce list (Bounces)
- Spam Reports list
- Unsubscribe list (Global Unsubscribes/Group Unsubscribes)
- Invalid recipient list
<Caution>
Even if the receiving environment is ready to receive, email addresses that have been "bounced" in the past will be "dropped" even if they are resend status.

<Caution>
If the problem on the receiving end has not been resolved, you may be bounced again even if you are removed from the list.
■ In the case of deferred
While "deferred" is listed in the List of Notification Errors, the system is resending the email. Please wait until the status changes or it disappears from the List of Notification Errors.
